known to be already authenticated, so it proceeds directly to key exchange
and association.
• To support pre-authentication, both clients and access points in the network
must be WPA2 enabled.
• Pre-authentication requires all access points in the network to be on the
same IP subnet.
Example
Link Integrity Commands
The access point provides a link integrity feature that can be used to ensure that
wireless clients are connected to resources on the wired network. The access point
does this by periodically sending Ping messages to a host device in the wired
Ethernet network. If the access point detects that the connection to the host has
failed, it disables the radio interfaces, forcing clients to find and associate with
another access point. When the connection to the host is restored, the access point
re-enables the radio interfaces.
